Toshiba MG Series 18TB Enterprise 3.5" SATA Hard Drive 7200RPM

Key specs

• Capacity: 18TB
• Form factor: 3.5-inch internal drive
• Interface: SATA (Serial ATA)
• Spindle speed: 7200RPM
• Duty cycle: designed for continuous 24/7 operation
• Deployment: RAID and high-density storage arrays

The Toshiba MG Series 18TB is a bare enterprise drive for integration into servers, NVR/NAS chassis or rack-mounted storage systems taking a standard 3.5" SATA bay — check the target enclosure has a free bay and SATA connector before spec'ing it into a build.

At 7200RPM the drive gives consistent throughput for sequential workloads: large file writes, backup jobs and continuous recording streams rather than high-IOPS random access. That makes it a fit for surveillance recording platforms, backup repositories and video archiving as well as general data centre storage.

RAID and multi-drive builds

Toshiba engineers the MG series for continuous operation in multi-drive environments, so it's suited to RAID arrays and high-density enclosures where several drives run simultaneously under sustained load — the scenario integrators hit on NVR storage expansions and DAS/NAS builds. For distributors quoting large-capacity surveillance storage or cloud/backup infrastructure jobs, the 18TB capacity point cuts drive count per array, useful when rack unit or bay count is the limiting factor.

No RAID controller, caddy or enclosure is included — this is the drive only, so confirm compatibility with the target chassis' bay size and interface before ordering.
